GATE-HINGE.

SPECIFICATION formingpart of Letters Patent No. 223,890, dated January 27, 1880. Application filed November '1. 1879.

Be it known that I, JAMES E. DAVIS, of Palmyra, in the county of Portage and State of Ohio, have invented a new and Improved Gate-Hinge, of which the followingis a specification.

Figure l is a side elevation of my improvement. Fig. 2 is a sectional elevation taken through the line at :r, Fig. 1.

This invention relates to the class of gates that. are opened by running them back and then swinging them around; audit has for its object to furnish a hinge so constructed that the gate may be very easily operated.

Theinvention consistsin a gate-hinge formed of a screw hinged to a pintle provided with a small pulley and placed Within a large ringpulley, as will be hereinafter fully described, so that the said parts may move freely upon each other and allow the gate. to be easily opened and closed, however heavy it may be.

Similar letters of reference indicate corresponding parts.

A represents a screw, through the extended head of which is formed a hole to receive the pintle B. The upper end of the pintle B is enlarged, and is slotted to receive the small pulley G, which pulley is pivoted to the said slotted end of the pintle B. The lower end of the pintle B has a V-shaped notch, D,formed in it, and the pulleyO has a V-shaped groove, E, formed in it. The notch D and the groove E of the gate.

receive the V-shaped inner side, F, of the ringpulley G, which pulley has asquare groove, H, formed in its outer side to receive the bars between which it is designed to roll.

In using the hinge the screw A is screwed into the gate and the ring-pulley Gris inserted between two stationary bars; or the screw A is screwed into a post or other support and the ring-pulley G is inserted between two bars In either case the gate is opened by running it back for apart of its length and then swinging it around.

. With these hinges heavy gates can be easily and quickly opened and closed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. As an improved article of manufacture, a gate-hinge made as herein shown and de scribed, and formed of the screw A, the pintle B, the small pulley (J, and the ring-pulley G, constructed and operating in connection with each other, as set forth.

2. In a gate-hinge, the Pin g-pulley G, formed with an angular inner side, F, to engage with the pintle B and pulley C, substantially as herein shown and described, to keep it in place upon the pintle B and pulley O, as set forth.
